The book is (fairly obviously) a genealogical portrait record of Bavarian nobility (or royal lineage) from about the 10th century onwards. Bavarian history being the convoluted assembly of ruling houses that it is, I'm not altogether sure what 'Domus Boicae' in the title, "A series of portraits of the noble house of Boicae', means.**

Irrespective of the true background to the series, I thought the book worth featuring for the beautiful engraving work by, or after designs by, the author, Joseph Zimmerman (d. 1797), an artist who received formal training in his chosen vocation in Regensburg and Augsburg [bio].

**Later: I've had it confirmed that the 'Boica' in the title refers, in fact, to the German state of 'Bavaria', so it's: 'A Series of Portraits of the Noble House of Bavaria'.
